ARTHUR F. SCI-IIELE, OF DURANT, IOWA.

INTERNAL-COMBUSTION ENGINE.

Application filed March 28, 1916.

To all whom it may concern:

Be it known that I, ARTHUR F. SCHIELE, a citizen of the United States, residing at Durant, in the county of Cedar and State of Iowa, have invented certain new and useful Improvements in Internal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to internal combustion engines, and has for its primary object to provide an improved type of rotary valve particularly designed for use in connection with engines of the explosive type, and embodying such novel features of construction as to render the engine more durable and efficient and more economical in the consumption of fuel.

WVith this and other objects in View, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which:

Figure 1 represents a fra'gmental sectional view through the upper portion of an engine, illustrating the improved valve, and operating means therefor,

Fig. 2 represents a plan view of the engine,

Fig. 3 represents a transverse sectional view on the line 3-3 of Fig. 1, and v Fig. 4 represents a transverse sectional view on the line 44 of Fig. 1.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the fragment of the cylinder of an internal combustion engine, having the usual jacket 6 providing the water chamber 7. The head 8 of the cylinder 5 is of inverted frusto-conical formation and constitutes a seat for the rotary valve, designated generally by the nu meral 9 and is connected with the upper-part or top 10 of the water jacket by a tubular connection 11, receiving a bushing 12, in which is rotatably mounted the valve stem 13 of Specification of Letters Patent.

the valve 9. The upper extremity of the valve stem 18 is mounted in a bracket 14 attached to the head of the jacket 6 and is formed with external screw threads. positely arranged bearing cones 15 are adjustably fitted upon the threaded terminal of the valve stem and engage friction reducing balls 16 arranged in holders 17 engaged with the top and bottom of the hori- Zontally disposed portion of the bracket 14.

Rotary movement is transmitted to the valve stem 13 and valve 9, during operation of the engine, by a shaft 18, connected with the crank shaft of the engine by a chain or other power transmitting device and provided with a worm 19 meshing with a pinion 20 non-rotatably engaged upon the valve stem 13 intermediate the head 10 of the water jacket and the bearing or bracket 14.

The head 8 of the cylinder is formed with spaced inlet and outlet ports 21 and 22, respectively, which are intermittently and successively uncovered by the port 22* in the valve during rotary movement of the latter, so as to admit an explosive charge to the cylinder 5 and permit of the exhaust of the products of combustion therefrom. The inlet port 21 is connected with a fuel pipe 23 and the exhaust port 22 is connected with an exhaust pipe 24.

What is claimed is:

In an explosive engine, a cylinder including a frusto-conical head, a water jacket ar ranged in spaced relation to the cylinder and connected therewith by a tubular extension, a conical valve mounted in said head, a stem carried by said valve projecting upwardly through said tubular extension, a substantially U-shaped bracket connected with said cylinder and rotatably receiving said stem, oppositely arranged bearing ball holders engaged with said bracket, bearing balls arranged in said holders, bearing members adjustably mounted on said stem and engaged with said balls, and means for rotating said valve and stem.

In testimony whereof I affix my signature.
